3 Claims. -v (CL 28o-106) 10 mounting is 'shown for use where, inassembling the automobile, the shock absorber is put on after the coilsprings are in place. Where, in some circumstances, it is desiredtoattach the shock absorber prior to positioning of the coil spring, ,Iit is possible to employ a different type of come struction. The objectof the present invention is to provide a simple and eiicient means ofattaching the shock absorber and one vwhich will allow its` readyremoval and reassembly without difficulty, and which may be used toattach the shock absorber either before or after the coil spring is inplace.

The accompanying drawing illustrates an emzbodiment of the invention andthe` views are as follows:

Figure 1 is a top plan view of an automobile frame'with a shock absorbermounted thereon; Fig. 2 is a bottom plan view of a section of the frameshowing the attachment;

Fig. 3 is a section on line 3-3 of Fig. 1 showing the coil spring inplace; and v Fig. 4 is a similar section ,on line 4-44 of Fig. 1. Theautomobile frame comprises, in general, a pair of side rails I, acentral X cross member 2,

a forward cross member 3 and a rear cross member 4.

. The forward cross member 3 is constructed for supporting the frontendof the frame on independent coil springs 5 as set forth in U. S.LettersPatent No. 1,965,561. The upper horizontal web 6 of the crossmember 3 is provided with a reenforcing plate 1 such as that set forthin the copending applicationabove referred to. There are two holes 8through the web 6 and plate 1, within the circumference of the springvseat, for the purpose of receiving bolts 9 for attaching the shockabsorber I0. The holes 8 are positioned accurately and preferably reamedfor accurately positioning the shock absorber. y Nuts II cooperate withthe bolts .9 in securing the attachment. For the purpose of facilitatingassembly, 'the nuts I I are held from turning by a plate I2 welded* tothe plate 1 and extending between the openings 8. The plate I2 has arecess at each end complementary to the nut I I for holding the' same`against rotation.

'Ihe nuts II are held within the recesses in` plate i2 prior to andduring assembly by means 5 of' a pan I3 which forms the seat for thecoil spring 5. 'I'he pan I3 is formed of sheet metal and is circular,with its flanged rim dening the seat for the spring. The central web ofthe pan I3 is provided with holes I4 beneath the nuts II 10 forreceiving the ends of bolts 9. The holes I4 are not of sulcient diameterto allow the nuts II to drop out when the bolts 9 are not in place.'I'he distance between the end of the nuts II and the pan I3 is lessthan the thickness of the plate 15 I2 so that the nuts will not escapefrom the recesses In the plate I2.

In assembling, the shock absorber may be attached either before or afterthe frame is seated on spring 5. When it is to be attached before, 20the nut II is held in the recess in plate I2 by hand while the bolt 8 isinserted through the base of the shock absorber and through one of theholes 8 and screwed into the nut. After the bolts 9 are tightened thepan I3 is put in place and the 25 coil spring 5 then seated in place.When the shock absorber is to be attached after the coil spring is inplace, the nuts II are rst positioned in the recesses in plate I2 andpan I3 applied to hold them there. 'I'hen the coil yspring 5 is put inplace, thereby holding the nuts II in a floating position beneath holes8 for subsequent convenient entering of the bolts 9.

The shock absorber may be removed at any time without danger of losingthe nuts I I, and the 35 construction facilitates reassembly.

Various embodiments of the invention may be employed within its spiritand scope as expressed in the accompanying claims.

\ I claim:

1. In an automobile in which the chassis frame is independently sprungwith respect to the wheels by means of coil springs, a shock absorbermounting comprising means attached to the frame and within the coilspring for holding the attaching .nut against rotation', and a panforming a seat for vthefcoil spring and serving to hold thenut in placeduring 'removal of the shock absorber.

2. In `an automobile in which the chassis frame is independently sprungwith respect tothe wheels by means of coil springs, a shock absorbermounting comprising a plate attached to the under side of the framewithin the coil spring and having a. recess for receiving an attachingnut and pre- .venting its rotation, a bolt passing through the u usfbase of the shock absorber and through the frame element into engagementwith said nut, and a pan forming a seat for the coil spring and servingto retain the nut in the recess in said plate when the bolt ls removedfor removal of the shock absorber.

lng comprising a bolt passing through the base of the shock absorber andthrough the frame element into engagement with a nut inside the coilspring, a pan forming a seat for the coil spring and serving to retainthe nut in place when the bolt is removed for removal of the shockabsorber, and means for preventing rotation of the nut.
